Introduction

Ethyl chloride or ethyl chloride is a colorless flammable gas with the molecular formula C2H5Cl, abbreviated as EtCl.

Physical and chemical properties

Ethyl chloride is a colorless gas with the smell of ether. It is flammable and produces phosgene and hydrogen chloride when exposed to flame. Used as chemical raw materials, anesthetics, refrigerants and pesticides, etc.

Chemical properties

It is a gas at normal temperature and pressure, and is a colorless, low-viscosity, volatile liquid at low temperatures or when compressed. Has an ether-like odor. Miscible with ether, soluble in ethanol (48.8g/100ml), slightly soluble in water (solubility at 20°C: 0.574g/100ml)

Usage

Ethyl chloride is an intermediate of the insecticide phorate, the fungicides ethosalin and ethocarb.

Usage

Mainly used as raw material for tetraethyl lead, ethyl cellulose and ethyl carbazole dyes. It is also used as aerosol, refrigerant, local anesthetic, insecticide, ethylating agent, olefin polymerization solvent, gasoline anti-seismic agent, etc. It is also used as a catalyst for polypropylene and a solvent for phosphorus, sulfur, grease, resin, wax, etc. Synthesis of pesticides, dyes, pharmaceuticals and their intermediates.

Production method: Industrial production of ethyl chloride generally uses the ethylene hydrochlorination method, a few use the ethane chlorination method, and a very few use the ethanol method.
1. Ethylene hydrochlorination method uses ethylene and hydrogen chloride as raw materials to carry out addition reaction. The technology and economy of this method are relatively reasonable, and there are two types: gas phase method and liquid phase method. The liquid phase method is to react high-concentration ethylene with hydrogen chloride in a solvent such as ethyl chloride (30-40°C, 253-303kPa) in the presence of a catalyst such as AlCl3, and then perform gas-liquid separation after alkali washing and distillation to obtain a pure product. The gas phase method uses AlCl3, NH4Cl, silica gel, etc. as catalysts, uses a lower concentration of ethylene and ethane mixed gas as raw materials, and reacts at 130-250°C.
2. Ethane chlorination method is mainly based on thermal chlorination method in industry, that is, ethane is chlorinated at 250-500℃ and pressure 202-304kPa (the by-product hydrogen chloride reacts with ethylene, and ethyl chloride can also be produced. alkyl).
3. The ethanol method involves the reaction of ethanol and hydrochloric acid in the presence of zinc chloride. Raw material consumption quota: ethanol (95%) 945kg/t, hydrochloric acid (30%) 2830kg/t, zinc chloride 90kg/t. In addition, ethyl chloride can also be obtained by absorbing the tail gas produced by hydrochloric acid, a by-product of the production of trichloroacetaldehyde, and drying it with 98% sulfuric acid, followed by pressurization, freezing, liquefaction, and distillation purification.

Production methods The preparation methods include the following.
(1) Addition of ethylene and hydrogen chloride This method is divided into two types: gas phase method and liquid phase method. Gas phase method: ethylene and hydrogen chloride are passed through aluminum trichloride and bismuth chloride catalysts at a reaction temperature of 130 to 250°C to obtain ethyl chloride, which is then distilled to obtain the product. CH2=CH2+HCl→CH3CH2Cl liquid phase method: Anhydrous hydrogen chloride and dry ethylene pass through a reactor equipped with vinyl chloride-aluminum trichloride liquid, react at 30~40℃, 245~294kPa pressure, and then flash evaporated, The product is obtained by alkali washing and distillation.
(2) Ethanol method: Ethanol and hydrogen chloride gas react by bubbling 70% to 80% zinc chloride aqueous solution to generate crude ethyl chloride. The hydrogen chloride contained in the ethyl chloride is then neutralized with alkali solution and dried with concentrated sulfuric acid. The water in ethyl chloride is removed, and the ether is washed away, and then the finished product is obtained by condensation. C2H5OH+HCl[ZnCl2]→C2H5Cl+H2O
